Virtual Pin more than 4

I tried to enable a simple template to command a led strip with and ESP8266

I’m able to correctly work with 4 virtual pin from v0 to v3, with the code below.
from the app, clicking on a button, I successful turn on the led.
I have a datastream for each virtual pin, and I need to use 6 virtual pin.

the problem is when I try to use a virtual pin following v3… like for example v6 or v10…
the event is not raised, and then I’m not able to execute the code when I push the button

where is my error ? :smiley:
